What this means for you Summary
Snapshot
- This is a 2 × 2-bed/?-bath units multifamily listed at $220k. Condition is rated fair.
Deal economics
- At list price, monthly cash flow is $939 ($11k/yr) — positive. Per door: $469/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($3k rent vs $220k).
- Recommended offer: $194k (12.0% below list) — sets the bar for market timing.
- Cap rate 11.4% vs local median 3.1% in Ottawa — top-decile yield for the area; either an underpriced asset or a hidden risk that comps aren't pricing in. Stress-test before assuming the spread holds.
Location & tenants
- Location reads 77/100 on livability (#172 in IL, #3,175 nationally) — a middle-class / working-renter tenant base. Strengths: cost of living A+, health & safety A+, housing A; Watch: employment C-, amenities D, commute F.
- Ottawa Twp Hsd 140 (town): math 25% / reading 30% proficiency, ranked #545 of 919 in IL (top 59%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover.
- Zoned schools: Ottawa Township High School (math 17% / reading 27%, grade F, #319 of 693 statewide, top 50%, 1,261 students, 0% FRL).
- Market conditions: 208 active listings in the ZIP; 2 comparable units currently listed for rent nearby; solid renter incomes; 82 units permitted in LaSalle County in 2024 (0 in 5+ unit buildings).
- At $3,113/mo this rent would consume 48% of the median local household income ($78k/yr) (locally 628% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.
Forward outlook
- Local home prices are declining (-3.0%/yr); year-one equity from $2k of loan paydown is wiped out by about $7k of value loss. Plan a longer hold.
- LaSalle County population projected at -16% by 2050 — secular population decline; favor cash flow + early exit over multi-decade hold.
- At projected returns (-3.0% appreciation + 3.0% rent growth), your $62k cash investment doubles in ~7 years — after that, you're playing with house money.
Negotiation context
- It's been on market 135 days — a 12% lower offer ($194k) is reasonable based on typical stale-listing flexibility.
Risks & watch-outs
- Watch-outs: built in 1920 — expect roof / HVAC / electrical / plumbing capex.
Questions for the listing agent
- It's been on market 135 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
- Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
- What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
- Have any recent inspections been done? Can we get a copy of the seller's disclosures and any deferred-maintenance estimates?
- Built in 1920 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
- Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
- Schools are D-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
- What's the average days-on-market for RENTAL listings here right now (not sales)? A rising rental-DOM trend means longer vacancies and softer asking-rent achievability than the comps imply.
- What's the recent tenant-quality profile in this submarket — average credit score on applications, eviction rate, late-payment / NSF rate, and stable-employment percentage? A property-management company in the area should have these aggregated.
- How much new apartment / multifamily construction is in the pipeline within 1–3 miles? Heavy new supply (>2% of stock underway) typically softens rents 12–24 months out; light construction supports rent growth.

For passive investors: Depreciation is non-cash, so a rental often shows a tax loss while cash-flowing — sheltering income. Rental losses are passive: they offset passive income freely, and up to $25,000/yr can offset ordinary (W-2) income if you actively participate and your MAGI is under $100k (phasing out to $0 by $150k); unused losses carry forward. On sale, claimed depreciation is recaptured at up to 25%, and gains may owe capital-gains tax (a 1031 exchange can defer both). Figures are a year-1 estimate at your 24.0% rate — not tax advice; consult a CPA.
